Effectiveness of Indigenous Lead (Pb) Reducing Bacteria Consortia of Waste Water Treatment in Agar Flour Industry

Lead (Pb) is known as toxic element in environment. It is produced from processing of Agar Flour industry activities. Enhancement of Pb in the waste water of agar flour is very dangerous for human health. Effect of lead damage some organ e.g. kidney, liver, and hair. Environment standard of lead concentration on waste water based on Governor of East Java Regulation No. 72 of 2013 is 1 mg.L-1, otherwise, initial lead levels of waste water are 3.114 mg.L-1. The aim of the research is reducing the level of lead to be harmless for the environment. One method to decrease a high concentration of lead in waste water is biosorption. Consortia of Bacillus alvei and Bacillus pumilus as indigenous bacteria are used to decrease Pb level in the wastewater. The experiment was carried out with varies of wastewater concentration and bacteria 3 %, 4%, 5%, 6%, and 7%. Consortium of B. alvei dan B. pumilus at 7 % concentration have the highest potency 93.58 % to reduce lead reach 0.2 mg.L-1

Pre-service biology teacher’s perception on local environment problems as contextual learning resources

A survey and exploratory study were conducted to analyze Lake Tempe as a resource for contextual learning (CTL). The first phase of the study included exploring the lake’s potential through interviews with the people who live in the lake’s coastal region. Quadrat transects were done to identify aquatic plants around the lake. A feasibility analysis was conducted to see the lake’s potential as a learning resource. Field data were collected and compared to the environmental biology (EB) curriculum, responses, and learning outcome. The data were analyzed descriptively and tested using a paired-sample t-test. The results showed differences in the three stations’ physicochemical parameters and decreased quality of the water. It was found that anthropogenic activity had a significant contribution to the lake’s pollution. Nine species of six aquatic plant families were found in the lake. The survey revealed that the lake was feasible as a learning resource with criteria easy to access, safety, time efficiency, costs, and the material's suitability for EB courses. The t-test showed a difference in the students’ scores between before and after exploration practices. These findings suggest that Lake Tempe can serve as a resource for CTL in EB courses
